I have a commercial tenant who has freezers which have turned off- they claim that the power board is at fault, but electricians say the power board is OK. They've lost a lot of food which was intended for charity recipients. A blown circuit breaker has been replaced; and although the power board is old, I'm advised it doesn't need replacement. I was wondering if it's possible to supply temperature monitoring to the site- the sort which sends out an SMS if the temperature goes above a given number. I can find ones in the US which are a reasonable price (< $100) but the ones I can find here are $400 for the monitoring plus $100 for each probe + mount. I'm not even sure how many freezers- but I was wondering if anybody had any experience with this sort of monitoring equipment?
I know a friend who was remotely monitoring his greenhouse...... I guess instruments like these?

That looks good. It doesn't require a separate probe, which makes it cheaper still. I'm guessing one unit per freezer. Does your friend actually use these units? In Australia? Thanks!
We remotely monitor the temperature of our food storage via an alarm system which dials our refrigeration mechanics in the event of a temperature increase. Note this is a high volume ammonia plant with several thousand pallets.
There is no requirement to replace or upgrade a switchboard if it complied with the standards at the time that it was installed. If the tenant installs a sub-board or additional circuits, these are to be compliant with the current regulations. If a circuit breaker tripped (or fuse blown) then it has done its job and protected the equipment (& your building) from damage. Have the tenant contact their electricity provider to check if there was a reported outage, to check/test their equipment & claim their losses on insurance. @The Y-man - the GSM network has been turned off in Oz. Any solution that you install should be NBN compliant for future proofing.
